Power Efficiency. Increased output efficiency, resulting in power cost savings

Reliable. Elimination of expensive finite life components such as the vacuum tube, RF output transformer and tank capacitors adds to increased reliability and up-time, and a significant reduction in maintenance costs.

Safety. Solid State welders operate at much lower voltages than vacuum tube units – not exceeding 1200 volts at full power assuring added safety operators and maintenance personnel.

Floor Space. Solid State welders are extremely compact, occupying minimal space. The power supply can be placed up to 1,000 feet away from the mill.

Improved contact wear. Due to less arcing.

Reduction in scrap. Due to improved automatic Speed Power Control, reducing unwelded fin areas when stopping and starting.
